Local Search around Midpoint of Route: This app searches for places to meet, around the midpoint of a route between two locations that you specify, using Google Maps. One could very well perform the relevant operations in the Google Maps app, and search for such places manually. But, that is usually makes for quite a pain in the neck (and thumbs). This app simplifies the process greatly.
mattcraiganon: Another reddit made app, rough around the edges and needs refinement but I urge you to support it. It'll allow you to find exact halfway locations when meeting friends. Dev needs to limit the places to actually sociable locations though!
